Apparently, someone was so inspired by S. Balachander's 1950s classic Andha Naal that he made a whodunnit thriller of the same name. Who?

In the recently released film Sasanam, Arvind Swamy plays a role with a bit of an autobiographical strain. How?

He plays Muthiah, a man who is adopted by a rich landlord, just like how he was adopted by an industrialist in real life.The film, directed by Mahendran, was completed years ago, but stayed in cans till its release.
